Yup, it would be dog eat dog.
My neighbors across the way have a gadsden flag and an obnoxiously loud whole house generator. Neighbor across from them also have a loud generator that kicks on in any power outage. My old farm house is a shambles compared to these folks with much nicer stuff apparent. No vehicles set out at my place. You'd be hard pressed to ever tell if there is anyone home or not.
Marauders will have many miles to cover before they get out our way, so we'll know they are coming. 104 yards to one neighbors drive, 133 to the other, from the cover of my back porch.
